John Fogerty will celebrate his 20th wedding anniversary with a visit to the bayou. He and his wife, Julie, will board a Mississippi River boat on Saturday in New Orleans. The boat will be renamed the Proud Mary for the day. Fogerty says even though they were married in Indiana, he couldn’t think of a better way to celebrate than to go to New Orleans with his children and friends. Fogerty will kick off a world tour in May. He and his wife are working on a literary project set in a southern swamp.
